Under the terms of your Clean Energy Council design accreditation, you are expected to adhere to the Clean Energy Council System Design Guidelines.
The following site-specific information is a minimum requirement to design a system:
- Occupational safety risks of the site
- Whether the roof is suitable for mounting the array
- Solar access for the site
- Whether any shading will occur and its estimated effect on performance
- Orientation and tilt angle of the roof
- Where the inverter will be located
- Location of AC switchboards
- Whether any switchboard or metering alterations are required.
The designer's responsibilities are to:
- provide full specifications of the system including quantity, make and model number of the solar modules and inverter
- provide a site-specific full system design including all shading issues, orientation and tilt, along with the system's site-specific energy yield, including average daily performance estimate in kWh for each month of solar generation
- ensure array design will fit on available roof space
- ensure array mounting frame installation will comply with AS1170.2
- ensure array configuration is compatible with the inverter specification
- ensure all equipment is fit for purpose and correctly rated
- obtain warranty information on all equipment.
Documentation that the designer is required to provide to the installer:
- A list of equipment supplied
- A list of actions to be taken in the event of an earth fault alarm
- The shutdown and isolation procedure for emergency and maintenance
- A basic connection diagram that includes the electrical ratings of the PV array and the ratings of all overcurrent devices and switches as installed
- Site-specific system performance estimate
- Recommended maintenance for the system
- Maintenance procedure and timetables
- If you run a sales company and engage accredited installers, someone in your company must be an accredited designer who takes responsibility for the system design and performance estimate for each job. If you do not take this responsibility, you need to inform the installer of this.
The reason that rebates and feed-in tariffs are paid to customers is primarily due to the greenhouse gas savings generated. It is critical to the future of the solar industry that this simple fact is not forgotten.
We all have a responsibility to ensure that the efficiency of solar systems is maximised, and an industry reputation for ethical behaviour and concern for the environment is maintained.
